A Block of Redstone is a mineral block that is crafted from nine Redstone. While it can be used as a decoration, it also has the unique property of being a solid block that always outputs redstone power, which can be useful for Redstone circuits, as it is the only power source that can be moved by a Piston. It is also the earliest form of permanent lighting, since it emits a light level of 11, making it very valuable early on to light up your base or keep a few animals alive in a pen.
